No IP communication over a VPN client connection (e.g. FRITZ!VPN)

Although a VPN connection is established, you cannot access network devices or services in the remote FRITZ!Box network with a computer with the FRITZ!VPN software or a computer with macOS. When a network device in the remote FRITZ!Box network is pinged, there is no reply.

Simply proceed as described below. After each measure, check whether the issue persists.

1 Correcting the network settings

If a LAN or wireless network adapter on the computer with FRITZ!VPN or macOS has an IP address from the FRITZ!Box's IP network, then VPN communication is not reliable. VPN communication is even disrupted when the connection to the network adapter is cleared.

Example:If the FRITZ!Box you would like to establish a VPN connection to is configured for IP network 192.168.178.0 (subnet mask 255.255.255.0), then no network adapter on the computer may use an IP address from the 192.168.178.xxx range.

Disable all network adapters with an IP address from the FRITZ!Box's IP network:

Right-click the respective network connection and select "Disable" from the context menu.

macOS

Open the Finder and click "Applications".

Click "System Preferences" and "Network".

On the left side, select the respective network adapter.

Click on the gear icon next to the plus and minus (+/-) symbols and select "Make Service Inactive".

Click "Apply" to save your settings.

2 Configuring parental controls to allow Internet access

You cannot access devices in the remote FRITZ!Box network over the VPN connection if the FRITZ!Box parental controls restrict the devices' Internet access. Therefore, make sure that the respective devices are allowed to access the Internet:
